Definitions

  • Forming an object of the present invention is a device for controlling a parking brake of a motor vehicle with handlebar, according to the preamble of the main claim.
  • a device for controlling a brake as described in the preamble of the main claim is disclosed in DE19510782A1 .
  • a parking brake As known, in a motor vehicle, there is usually present a parking brake.
  • the expression "motor vehicle with handlebar” is used to indicate a two- or three-wheeled motorcycle, a scooter, a snowmobile or the like, the control of the parking brake is obtained mechanically, through a lever suitably provided on the vehicle or through a button arranged on the handlebar.
  • an object of the present invention is to provide a lever device of the aforementioned type that meets such need.
  • an object of the present invention is to provide a lever device of the aforementioned type that allows the actuation of parking brakes acting with medium- or large-size braking members (callipers) without the user applying a high force to move the lever.
  • Another object is to provide a lever device for the engagement or release of the parking brake in an electric drive vehicle with handlebar wherein such lever can be easily reached by the rider.
  • Another object is to provide a device of the aforementioned type which has the possibility of indicating to the rider of the motor vehicle with handlebar whether or not the parking brake is engaged (or actuated).
  • a lever device for manually controlling the engagement or disengagement of a parking brake, (not shown) in a motor vehicle with a handlebar (also not shown), in particular a vehicle with electric motor such as a two- or three-wheeled motorcycle, a snowmobile, a personal watercraft or the like is shown in the attached figures, and it is indicated with 1.
  • lever 8 From the box-like body 2 there protrudes a lever 8 whose actuation, by the rider of the vehicle mentioned above, allows at least to manually engage the parking brake.
  • the lever 8 is pivoted to the box-like body 2 on a pin 10.
  • the rider can engage the parking brake simply by acting on a lever (lever 8) arranged on the handlebar in a position that is easy to reach and with usual movements for a rider riding a motor vehicle provided with a handlebar, such as for example a motorcycle or a snowmobile.
  • a lever lever 8 arranged on the handlebar in a position that is easy to reach and with usual movements for a rider riding a motor vehicle provided with a handlebar, such as for example a motorcycle or a snowmobile.
  • such intervention for engaging the brake does not require great force by the rider: this is obtained by providing the serrated edge 13 and the serrated section 15 with an appropriate number of teeth which allows a multiplier ratio - in the cooperation thereof - so as to be able to actuate the brake callipers of relatively significant size.
  • such ratio may be 1/3 or 1/5, providing for the serrated edge 13 broader than the serrated section 15. In this manner, with a limited stroke of the lever, the rider exerts even a relatively significant force on the brake.
  • the invention provides a device that is simple to implement to engage the parking brake and that is intuitive to use by the rider.
